I don't give a toss what you call them but they are a PITA.
Cost Councils i.e. tax payers, a small fortune to clear up after them and in mostly futile attempts to stop them invading public spaces, which they then foul up. Farmers too are firced to blight the countryside with any means at hand to stop these freeloaders, who no doubt when ill, are first in line at A&E and when their roaving days are over, expect their kids to be educated at facitilies provided by others or live in public provided housing. Not to mention their crappy vans, which I simply do not believe would pass the MOT test that the lawabiding are forced to adhere to.
There's nothing racist about it.
I don't mind them opting our if they can find someone to provide a suitable field for free buit don't then expect to take advantage of the facilities provided by the hard work of other. If you want to live in the stoneage, then that's your choice but you can't expect to have it both way and be welcomed.
